To all whom it may concern Be it known that we, CHARLES WAGNER, a

,citizen of the United States, residing at Grantwood,'countyof Ber en, and State of New Jersey, and AUGUST ORMEL, a citizen of the United States, residin at New York city, county and State of ew York, have invented certain new and useful Improvements in Paper-Curing Machines, of which the following is a speclfication.

This invention relates to a novel machine I for curing paper, and more particularly for curing such pa er as is subsequently used for multicolor hthographic printing. As is well known, all paper either shrinks or expands owing to changes in the temperature,

etc., so that the consecutively imprinted patterns or designs of different colors will not register unless the paper has exactly the same temperature as the press room of the printing establishment. Our improved machine is designed to be installed within the press room and the air of this room is for a certain length of time blown against the paper to be subsequently printed. For this purpose a bipartite housing of novel construction is provided into a chamber of which a plurality of sheets of paper are introduced to be there subjected to the action of a number of blowers.

The invention also comprises other novel features of construction more fully pointed out in the appended specification and claims.

In the accompanying drawing, Figure 1 is an end view of a paper curing machine embodying our invention; Fig. 2 a longitudinal vertical section thereof; Fig. 3 a plan view of Fig. 1; Fig. 4: a vertical cross section on line 4+4, Fig. 3; Fig. 5 a horizontal cross section. on line 5-5, Fig. 1; Fig. 6 an end view partly in section of a machine showing modified paper-suspending means; and Fig. 7 a side elevation of the automatic paper-delivery device.

Our improved paper curing machine comprises essentially a pair of opposed spaced housings 10 forming a paper curing chamber 11 therebetween. Each housing 10 is com osed of a pair of upright 'end frames sheets 15 are secured to the flanges 16 of a middle frame 17 The inner verticaledges of the frames 12 of each housing are connected by an open-meshed wire netting 18 constituting an inner wall. The opposed end frames 12 of the two housings thus formed are connected with'each other by .trated in Figs. 1 to 5, said rails extending considerabl beyond the housings as at 21 and 21 ach of these rails is firmly attached to a bracket 22 of the frame 12 of each housing near the top thereof while at its middle, said rail is supported by the slotted head 22 of a bracket 23 forming part of frame 17. An eye 24 provided at the bottom of this frame is engaged by a post 25 the upper end of which is fitted into an eye 26 of bracket 23 to which last named eye the bolt is clamped by a nut 27. To increase the stab ility of the housings, the end frames thereof are connected by stay bars 28 that also pass through corresponding perforations of the middle frames 17.

Along the rails or track 21 is adapted to travel. a truck 29 from which the paper sheets 30 to be cured are suspended. Although we have shown but one truck in the drawings we desire it to be distinctly understood that we employ in practice two of such trucks, one for supporting the paper while being cured, while the other truck is shifted upon either of the protruding track portions 21 and 21 for removing the previously cured paper from said truck and then charging it with fresh paper.

Each truck 29 comprises a pair of transverse axles 31 upon the ends of which flanged wheels 32 are loosely mounted that engage rails 21. The axles 31 are firmly connected by means of a pair of longitudinal braces 33 secured to said axles by clamps 341. Upon the axles 31 are adjustably mounted the sleeves 35 of a pair of longitudinal bars 36 of a length that is slightly less than the length of housings 10. Each bar 36 is shown to be provided with a notched lower rib 37 each notch 38 being adapted for the reception of one or more sheets 30 of the paper to be cured whereby the paper is held in position by upwardly movable eccentric clamps or dogs 39. After a truck 29 has thus been charged it is movcd into a position betweenthe two housmgs r to be here subjected to a heavy draft. For producing the latter there is mounted 1n each housinga pair of rotatable blowers -that throw the press room air from both sides against the suspended paper sheets and thereby cause'the latter to assume the press room temperature in comparatively short time. Each of these blowers is shown to comprise a longitudinal shaft 41 mounted in corresponding bearings 42 of the end frames 12. Within housing 10 there 1s mounted upon shaft 41 in proximlty to each end frame as well as at 1ts middle, the hub 42 of a disk 43 provided with substantially radial flanges or ribs 44. To the latter are secured by means of screws 45 or otherwise, sheet metal vanes 46 the lnner edges of which abut'against the shaft 41 while their outer ends are slightly curved as clearlyillustrated in Fig. 4. All of the blowers 40 receive simultaneous rotatlon from a main driving belt 47 engaging a pulley 48 mounted on the lower right hand blower shaft 41 (Fig. 1). A belt 49 transmits rotary motion from the shaft 41 to the super osed shaft 41 which is in turn by means 0 a suitable belt transmisslon 50' connected to the upper shaft 41 of the opposite housing 10, said shaft beingco'nnected to the blower shaft 41 by belt 51. It will be seen that by the construction described all of the blowers 40 are simultaneously actuated to throw the air from opposite sides against, and between the paper sheets sus ended therebetween, thus effecting a quicl reliable and uniform curing of the same.

In lieu of suspending thepaper to be ofvopposed inwardly opening spaced cured from reciprocative trucks 29, a pair of continuously advancing endless carriers 52 supported by sprocket wheels 53 may be employed as illustrated in Figs. 6 and 7. Each of these-carriers comprises a plurality of links 54 which links are supported along the lower carrier run by flanged guides or tracks 55, the sprocket wheels 53 and guides 55 being laterally adjustable so as to adapt the machine to paper sheets of different width. Each link 54 is provided with a clamp 56 into which one or more paper" sheets 30 are manually or otherwise inserted, the finger 57 of each clamp being automatically opened at the end of the lower carrier run by an arm 58 so as to release the cured paper, the freed sheets being received by a suitable truck T.

For operating the carriers 52 a horizontal power shaft 59 is provided that transmits its motion through a speed-reducing worm gear 60 to a vertical shaft 61. The latter .5 drives in turn a horizontal shaft 62 by means ofa speed-reducing worm gear 63 that may be coupled to said last named shaft by a hand lever 64. The shaft 62 finally drives one of the shafts 65, supporting. the sprocket wheels 53. by means of stepped pulleys 66 and a belt 67. It will be seen that by the construction described, the paper, sheets 30 upon being manually or otherwise attached .to the carriers near the beginning of their lower run, travel slowly through the paper curing chamber to be automatically released at the end of such lower run after having assumed a temperature equal to that of the press room.
